If you are situated near Bedford, then it makes sense when booking same day courier services select a same day courier near Bedford.
The same applies whatever area you are in, as the couriers will already have vehicles in your area ready to collect. It also has the added bonus that you can benefit from backloaded deliveries which is where a vehicle would otherwise return empty. This is especially useful where items need to be collected from big cities such as London or Manchester and delivered to Bedford.
